通信設(shè)備中內(nèi)存管理優(yōu)化

通過(guò)對(duì)內(nèi)存管理的分析，提出了內(nèi)存優(yōu)化算法。該算法解決了通信設(shè)備中由于大量消息的發(fā)送導(dǎo)致內(nèi)存管理的問(wèn)題，建立了用戶(hù)定義的內(nèi)存管理區(qū)域，設(shè)計(jì)了新的內(nèi)存管理隊(duì)列，根據(jù)消息塊的大小配置內(nèi)存結(jié)構(gòu)，并給內(nèi)存塊加保護(hù)區(qū)域，從而提高了內(nèi)存資源的使用效率，盡可能地杜絕了內(nèi)存碎片。

Abstract This paper brings forward an optimizing memory algorithm by analyzing memory management. In communications equipments, memory management problems are often raised by mass message flow. The algorithm puts forward a series of solutions on these problems, including building user-defined memory management zone, designing optimized management queue, configuring memory structures according to the size of messages and providing protections on memory block. This design improves usage efficiency of memory resources and put an end to memory fragmentations as possible.
